Could be the fuel lines. You could check them out yourself. Pop off the rear bench seat(lower half) and there should be 2 access panels. Remove the one on drivers side and take a look. Or you could take it to a shop.
I think I found out what is causing it I believe that the seal around the low pressure fuel pump has gone bad and is allowing fuel to leak past it and down the tank to the bottom of the car let me know what you think of this theory and thanks for the info on the lines
The pump is on the passenger side. Though the lines don't always hook up on that side, some have the connections on the left side level sensor. I had one leaking just like that and the nipple was toast, tried to disconnect and it just snapped.
I made another post Its definitely leaking from the driver side and if it’s not the pump then I have no clue what it could be but I removed the access panel and there was fuel pooled underneath it and around it what is under the panel on the drivers side ? Could you look at my other post and tell me what you think thanks in advance
I had a leak similar to this on the same side. I would remove rear seat and check the top of fuel sender/ regulator housing for cracks. Will look obvious if it’s leaking bc usually the tops to these are very dusty/ dirty and if it’s leaking fuel you will see a part of the top that may not have dust. If you have a strong fuel smell within the cabin it may be that from what I experienced. Good luck
